CARDINFG-M-AICHINE.

SPECIFICATION forming part of Letters Patent No. 709,980, datedSeptember 30, 1902. Application filed February 4, 1901. SerialNo.46,017. (No model.)

To all whom it 71mg concern: 7

Be it known that I, HUBERT GILLJAM, spinnery proprietor, asubject of theKing of Prussia, residing at Laurensburg, near Aix-la- Chapelle, Kingdomof Prussia, in the Empire of Germany, have invented certain new anduseful Improvements in Carding-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the-invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My present invention relates to cardingmachines, and principally to adevice therein for thoroughly cleaning automatically thecarding-cylinder and keeping it clean during work, so that the frequentintervals of rest at present necessary for cleaning the clogged teeth ofthe carding-cylinder and rollers are avoided, and thereby the capacityof the carding-machine enhanced. 7

In the accompanying drawings, Figure 1 is a side elevation of acarding-machine provided with my invention. Fig. 2 is a longitudinalsection of the machine. Fig. 3 is a plan View of the grooved flange andother parts of a differential friction-clutch. Fig. 4 is a longitudinalsection of said clutch.

The frame of the machine comprises the two side parts 1 and 2 and thecross-pieces 3,1 firmly bolted to said side parts. The cardingcylinder 4rests in journal-boxes 5 on the elevated portions of side parts 1 and12and rotates in the direction indicatedby an arrow. The shaft 6 of thiscarding-cylinder projects beyond both of its journal boxes 5. The end ofshaft 6 projecting over the side part 2 of the machine-frame is providedwith the two pulleys 7 and 8, of which pulley '7 is the drivingpulley,and as it has a very broad face it serves likewise to carry thedriving-belt 9 for the stripping-rollers 10, dust-rollers 11, and volant12. In order to carry this belt 9 over the driving-pulleys of theabove-mentioned rollers, so asrnot to touch the under side of pulley 7,an adjustable idler 13 has been arranged on the outside of themachine-frame to serve this end in View and as a means to regulate thetension of belt 9. The direction of rotation of these rollers, pulleys,and belt is indicated by arrows. Next to the pulley 7 is seated pulleyS, transmitting motion from V the shaft6 to the shaft 14 by means of thebelt 15, running upon the pulley 16 on shaft 14. On the opposite end ofshaft 14 are seated the two pulleys 17 and 18 and the ropepulley 63. Thepulley 17 is larger than pulley 18, and both are connected by belt withthe differentialfriction-clutch 19, seated upon shaft 20 of thecleaning-roller 21.

The end of shaft 6 projecting beyond the side part 1 of themachine-frame is provided with a pulley 22, and over it runs a belt 23,

driving the working rollers 24 in the direction indicated by theirarrows. This belt 23 runs likewise over an adjustable idler to providemeans to regulate its tension.

. The feed-rollers 25 receive their motion from'pulley 26 on shaft 14 bymeans of the belt 27, which drives the upper of said feedrollers, whilethe lower feed-roller receives its motion from the upper feed-roller bymeans of toothed wheels. The doifer 28 receives its motion from anindependent belt 29. The shaft of the doft'er rests in adjustablebearings and is provided with a pulley 30, upon which the open belt'3lruns, imparting motion to the stripper 32, likewise journaled inadjustable bearings; 'At'the end of the machineframe is adjustablyarranged the doff- 'ing'or detaching knife 33, which takes the materialoff the stripper 32.

' In operation the material to be carded is thrown upon'the endlesstable 34, driven by the lower of the feed-rollers 25, by means oftheiwheel 35, meshing with the wheel of the l oWer'feed-roller and withthe wheel 36 upon the shaft 37 of the driving-roller 38 of said endlesstable. As soon as the material has reached the feed-rollers it iscarried by them to the circumference of the carding-cylinder 4 andundergoes the process of carding. The material to be carded is partlyremoved by the first working roller 24, running in opposite direction tothe cylinder 4, and in turn taken off the working roller by thestrippingroller 10, running in the same direction as saidcarding-cylinder, but with greater circumferential speed than theworking roller 24. Besides running faster than the working roller 24 theteeth of the stripping-roller 10 enter the teeth of roller 24 to acertain depth, so that the teeth of the latter are always kept clean.The circumferential speeds of the ICO working roller 24 and of thecylinder 4 are equal. By running faster than the working roller 24 theroller 10 will take the material off the roller 24 and depositit againupon the face of the cylinder 4. This play repeats itself until aftermany manipulations the carded fleece reaches the volant 12, which liftsthe fleece out of the teeth of the cardingcylinder, but lets it restupon them. Afurther advance of the cylinder 4 brings the fleece to thedoffer 28, by which itis taken otf said cylinder and carried to thestripper 32, whose teeth enter the teeth of the dofler 28, so that thewhole of the fleece is taken off the doifer and carried to the doffingor detaching knife 33, from whence the fleece is carried to a pointwhere it undergoes further manipulations.

Although the teeth of the doffer may be ever so nicely adjusted to thecircumference of the carding-cylinder, a portion of the fleece willremain in the teeth of the latter, and it is clear if this remnant ofthe fleece is not removed each revolution of the carding-cylinder willadd to the matter clogging its teeth, and in more or less time athorough cleaning of the teeth of this cylinder will become a necessity.To avoid such cleaning and the therewith-connected loss of time andmoney, I have constructed a simple and yet efficient device toaccomplish this cleaning task while the machine is at work. To this endI have designed the differential friction clutch. (Shown in Figs. 3 and4.)

Upon the end of shaft are seated the fixed cone 39 and the adjustablecone 40, each provided with a friction-band of leather or of soft metal.The hub of the cone 39 carries the belt-pulley 41 and the rope-pulley42. Pulley 41 is provided with a conical face 43, suitable to engage thefriction-band of cone 39. The spring 44 tends to separate the pulley 41and cone 39 and likewise shifts the rope-pulley 42 on the hub of cone39. The face of the rope-pulley 42 next to the ring 45, inserted in thepulley 4G, is provided with an annular groove or race in which runs aball 47. Said ring is provided with a corresponding groove, comprising ashallow portion 48 and a deeper portion 49. The pulley 46 is slidinglyseated upon the hub of the cone and stands under the influence of thespring 50, tending to press the conical seat 51 of pulley 46 upon thefriction-band of the cone 40. The set-screws 52 serve to adjust the cone40 upon the shaft 20, and the holes in the webs of pulley 46 and cone 4Oserve to gain admit tance to said set-screws; but the holes in the webof pulley 46 may be omitted, as the collar 53, spring 50, and pulley 46can be removed, if necessary.

All parts having attained the positions shown in Fig. 4, the pulley 41drives the shaft 20. In this position the ball47 is held in the shallowportion 48 of the ring and in the groove of the rope-pulley 42, whereinthe ball will remain until it has reached the beginning of the deeperportion 49. As soon as this takes place the stronger spring presses thepulley 46 upon the friction-band of the cone 40, whereas now the spring44 will drive the pulley 41 off its seat and move the ropepulley towardthe pulley 46. At the moment this change takes place the shaft 20 willbe driven with a greater velocity than during the time it was driven bypulley 41, owing to the greater diameter of the pulley 17, drivingpulley 46, as compared to the smaller diameter of the pulley 18, drivingthe pulley 41. During this interval of time the pulley 46 is driving theshaft 20 and its roller 21, the latter running at its highest speed, andas its circumferential velocity is greater at this speed than thecircumferential velocity of the carding-cylinder and as the teeth of theroller 21 enter into the teeth of the carding-cylinder 4the teeth of theformer will remove all the remaining particles of the fleece left in theteeth of the carding-cylinder 4. This condition lasts until the ballreaches the shallow portion 48, bringing about a state of things asillustrated in Fig. 4 and described above, when the circumferentialvelocity of the roller 21 will be slower than that of thecarding-cylinder and the teeth of the latter in a position to take theparticles of the fleece out of the teeth of the cleaning-roller 21 andcarry them upward to take part again in the cycle of carding operations.

The depths of the portions 48 and 49 are so chosen that when one pulleydrives the other must of necessity leave its seat. The arrangement ofthe parts shown in Fig. 4 clearly shows that in this case the strongerspring 50 cannot press the pulley 46 upon its seat, being prevented fromdoing so by the ball 47; but as soon as the ball enters the deeperportion 49 the pulley 46 will be pressed upon its seat, and the weakerspring, being not any longer opposed, disengages pulley 41 and cone 39.The rope-pulley 42 is driven independently by a rope-pulley 63 uponshaft 14, and by choosing suitable diameters for these ropepulleys theperiods of changing may be regulated to suit any individual case.

In order to regulate the intervals of change from the faster to thelower speed of shaft 20, or vice versa, the length of the shallow anddeeper portion of the groove in the ring 45 may be proportioned at will.The object in dividing said groove into different lengths is to have thecleaning period last longer than the time during which the withdrawnmaterial is redeposited upon the carding-cylinder 4 in order to takepart again in the cycle of manipulations above described.

The dust-rollers ll serve to return any particles of the materialescaping from the v0- lant l2 and from the cleaning-roller 21 to thecarding-cylinder.

As the well-known parts of the carding-machine-such asstripping-rollers,working rollers, doifer, &c.--and the manner of theiradjustment form no part of my invention, they IOC have only beenmentioned to sufficiently explain the general working of the machine, buare clearly'indicated in the drawings.
